Description: this file contains the implementation of the "contraharmonic filter" using the basic formula of finding contraharmonic mean achieved through the use of for loops.
contraharmonic filter can remove both -SALT n PEPPER noise from the image but not simultaneously.
The positive order contraharmonic filter removes the pepper noise and the negative order removes the salt noise.
SALT n PEPPER noise has been added to the image and it has been removed sequentially using the contraharmonic filter of positive and negative filters one after the other.
It has been observed that the removal of salt noise followed by the removal of the pepper noise gives better results-this file contains the implementation of the "contraharmonic filter" using the basic formula of finding contraharmonic mean achieved through the use of for loops.

Description: REMOVAL OF NOISE FROM ECG (ELECTROCARDIOGRAPHY) BY USING MATLAB.
EEG (Electroencephalograph) recording from the scalp has biological artifacts and external artifacts. Biological artifacts, which are generated, can be EMG (Electromyography) signal, EOG (Electrooculograph) signal or ECG (Electrocardiograph) signal. These artifacts appear as noise in the recorded EEG signal individually or in a combined manner. Usually physicians are misled by these noisy signals and the EEG analysis can go wrong. This paper presents noise cancellation i.e. removal of noise signal which can be either EMG, ECG or a combination of these two artifacts from the corrupted EEG signal and also signal enhancement both using recurrent learning technique. For this purpose, we have implemented the RTRL (Real Time Recurrent Learning) algorithm,
